Hyperbaric Oxygen Therapy (HBOT) is the service rendered when a physician administers and supervises HBOT. Time is calculated based on the period of physician supervision while each patient receives HBOT inside the chamber. The specific elements of HBOT are those of an assessment, including ongoing monitoring of the patient's condition and intervening as appropriate. This code, G801, is for each quarter-hour or major part thereof of physician attendance in the chamber with the patient, after the first quarter-hour. This service is billed in sequence after G800 and is applicable for up to 2 hours of total chamber time. For time exceeding 2 hours, G802 is used.

The service is eligible for payment only if the start and stop times of the service are recorded in each patient's permanent medical record.
